Call for Participation: Collaborative Benchmarking of Functional-Structural Root Architecture Models. The Case of Root Water Uptake.

ABSTRACT: Three-dimensional models of root growth, architecture and function are becoming important tools that aid the design of agricultural management schemes and the selection of beneficial root traits. However, while benchmarking is common in many disciplines that use numerical models, such as natural and engineering sciences, functional-structural root architecture models have never been systematically compared. The following reasons might induce disagreement between the simulation results of different models: different representation of root growth, sink term of root water and solute uptake and representation of the rhizosphere. Presently, the extent of discrepancies is unknown, and a framework for quantitatively comparing functional-structural root architecture models is required. We propose, in a first step, to define benchmarking scenarios that test individual components of complex models: root architecture, water flow in soil and water flow in roots. While the latter two will focus mainly on comparing numerical aspects, the root architectural models have to be compared at a conceptual level as they generally differ in process representation. Therefore, defining common inputs that allow recreating reference root systems in all models will be a key challenge. In a second step, benchmarking scenarios for the coupled problems are defined. We expect that the results of step 1 will enable us to better interpret differences found in step 2. This benchmarking will result in a better understanding of the different models and contribute toward improving them. Improved models will allow us to simulate various scenarios with greater confidence and avoid bugs, numerical errors or conceptual misunderstandings. This work will set a standard for future model development.

Project description:Although researchers have used phone surveys for decades, the lack of an accurate picture of the call opening reduces our ability to train interviewers to succeed. Sample members decide about participation quickly. We predict participation using the earliest moments of the call; to do this, we analyze matched pairs of acceptances and declinations from the Wisconsin Longitudinal Study using a case-control design and conditional logistic regression. We focus on components of the first speaking turns: acoustic-prosodic components and interviewer's actions. The sample member's "hello" is external to the causal processes within the call and may carry information about the propensity to respond. As predicted by Pillet-Shore (2012), we find that when the pitch span of the sample member's "hello" is greater the odds of participation are higher, but in contradiction to her prediction, the (less reliably measured) pitch pattern of the greeting does not predict participation. The structure of actions in the interviewer's first turn has a large impact. The large majority of calls in our analysis begin with either an "efficient" or "canonical" turn. In an efficient first turn, the interviewer delays identifying themselves (and thereby suggesting the purpose of the call) until they are sure they are speaking to the sample member, with the resulting efficiency that they introduce themselves only once. In a canonical turn, the interviewer introduces themselves and asks to speak to the sample member, but risks having to introduce themselves twice if the answerer is not the sample member. The odds of participation are substantially and significantly lower for an efficient turn compared to a canonical turn. It appears that how interviewers handle identification in their first turn has consequences for participation; an analysis of actions could facilitate experiments to design first interviewer turns for different target populations, study designs, and calling technologies.
